I'm rebuilding the front strut assy. And was wondering about the dust shields. I am doing the Toyota caliper swap so I have to cut them anyway. I was contemplating not putting the dustshield back on. Now, I know that they are there to prevent dirt, water and other debree from coming into contact with the rotor but is there any other reason to keep the dust shield? Any opinions?

The dustshields do a really good job of retaining heat in the rotors and pads. So if you're always hard on the brakes, it makes it easier for them to fade quicker!

I've had mine off for almost 9 months now. Now noticable problems yet. Not that much extra dust on the wheels either. I say rip 'em off and use them for frisbees...
